Abstract

Fifty children aged 6 to 13 years and infected with Ascaris lumbricoides were selected for the study. The number of eggs laid daily by a female Ascaris increased with increase in its length, weight and diameter. Female worms became mature and started laying eggs when they reached a length of 118 mm. Adult female worms measuring 3·7 mm or more in diameter were found to be mature. The minimum weight of a worm producing eggs was 1·1 g. On average the number of eggs produced by the female decreased with increase in the worm load.
